Eosinophilic activity and bronchial hyperresponsiveness within an asthmatic paediatric population

ABSTRACT

Background: Our study aims to assess the importance of serum eosinophil cationic protein (ECP) levels as a non-invasive marker of bronchial hyperresponsiveness (BHR) in children with asthma, and may predict objectively the asthmatic severity and sensitivities. Methods: This study, which was carried out on 75 asthmatic patients from a paediatric population (average age: nine years old, sex-ratio M/F: 1.64), is based on both interrogation conducted by the clinician and biological explorations, essentially serological testing of ECP and eosinophilia determination, as well as the measurement of serological IgE amounts. Results: The analysis of the questionnaires and the biological results allowed us to evaluate the clinico-biological relations within this population. ECP, more than eosinophilia, proves to be a relevant marker of asthma severity (p<0.05) and sensitivities within this given population (r=0.65). Conclusion: We were able to show that the evaluation of the serological levels of ECP seems to be a good biological marker of asthma(AU)
